1. Pop the last element of given array In this example, we will take an array with four items. We call array_pop() function with the array passed as argument. We’ll then store the value returned by array_pop() function and print it. Also, as the original array gets modified, with...
You can use the array_pop() function to remove an element or value from the end of an array. The array_pop() function returns the last value of array. If the array is empty (or the variable is not an array), then the returned value is NULL.This...
""; // Now the current element is Glennecho reset($people) . ""; // Moves the internal pointer to the first element of the array, which is Peter echo next($people) . ""; // The next element of Peter is Joe print_r (each($people)); // Returns the key and value of the cur...
lengthOptional. Numeric value. Specifies the length of the returned array. If this value is set to a negative number, the function will stop slicing that far from the last element. If this value is not set, the function will return all elements, starting from the position set by the start...
array_column() 返回输入数组中某个单一列的值。 array_combine() 通过合并两个数组来创建一个新数组。 array_count_values() 用于统计数组中所有值出现的次数。 array_diff() 比较数组,返回差集(只比较键值)。 array_diff_assoc() 比较数组,返回差集(比较键名和键值)。 array_diff_key() 比较数组,返回差集...
